They have claimed something that makes it necessary. It was claimed that LLMs will 'soon' be able to 'write high quality books for us about each field'. If you can't produce a single insight on the topic, any book you write is going to fundamentally be a (very high level, likely almost verbatim) rehash of others, and therefore wouldn't usually be considered high quality. Not to mention the fact that an inability to generate real insight is indicative of a lack of an underlying model that isn't overfitted to the language used to express the examples.

I'm glad not, because I wouldn't be sure what they mean by that.
> a subject matter expert doesn't need a model to tell them anything insightful
Indeed not. Having existing ideas be juxtaposed, recontextualised or even repeated can be valuable. But to claim that AI will be writing entire books that are worth reading seems laughable to me. There's no sign that we're close to that. Just play with the state of the art models for a while and try and push them.
I'm convinced that anyone who believes otherwise just doesn't have the technical expertise (and that's not a generic insult; it's true of most of us) to probe deeply enough to see the fragility of these models. They look at the output and (erroneously, due to the unknown unknowns involved) think themselves perfectly qualified to judge it high quality — and they do so, with great vigour.
If your only claim is simply 'LLMs can remix natural language in a way that sometimes proves useful', then fine. I absolutely agree.
